3 claims. (ol. 177-329) Y t is desirable with automobiles to indicate the intention of the operator to turn and it is also desirable to have the device such that it may be conveniently actuated by the operator. The

present invention is designed to effect this purpose. Features and details of the invention will appear from the specification and claims.

1 marks the case. This is ordinarily secured to the side 2 of the automobile body. Bmarks the cover. This is pivotally mounted on the case bymeans of a pivot bolt 4. A link'5 is pivotally connected at 6 with the cover and by a pin 7 with a link 8. The link 8 is pivotally connected to the case'at 9. A link 10'is connected at 10a with the link 8 and at 11 with a lever 12. The lever 12 is iulcrumed at 13 on a post 14 carried by the case.A The lower end of the lever is connected With a lever 15 by a pin and slot connection 16. The lever 15 is fulcrumed at 15a on a post 15b extending from the case. The upper end of the lever 15 has a slot 17 through which a crank pin 18 extends. The crank pin is carried by an arm 19 and the arm 19 is iixed on a shaft 20. A gear 21 is 4also xed on theshaft 20 and meshes with a gear 22. The gear 22 is mounted on a shaft 23 extending from a motor frame 24. The gear 22 `is xed with a gear 25 and the gear 25 meshes with a gear 26. The gear 26 is mounted on a shaft 27 Anates'in a slotted end 49, the slot of `which en- Which forms the rotor shaft 29 mounted in the `frame 24. The link movement which is described as being driven by vthe motor is designed to open and Vclose the cover as the Amotor is reversed. Wires 30and v30a-are controlled lby a switch 31 50" and are connected, or disconnected, by the switch with a wire 32 extending to a battery 33; A Wire 34 extends from the battery to a post 34al grounding the line 34. The'wires 30a and 30 lead to posts 35 and 36 respectively and these posts have 55 spring contact plates 37 and 37a respectively. -A

, swinging contact finger 381s adapted to engage and form contact with theY contact plates 37a and 37. j

The finger 38 is mounted on a pin 39. An insulating disc 40 is connected with the nger 38 in a manner hereinafter described. 'Ifhe disc 40 carries reversing contact segments ,'41 and 42 Y vwhich operate over contact pins 43 andv 44 re- Spectively. The pins 43and 44 are connected yb .75 Wires45 and 45a with the brushes of the motor. The pin 39` extends A'through a squared hole inv the plate 24a of the motor frame 24 and the pins 43 and 44 extend through openings in an insulated plate 47. Ar pin 46a similar tothe pin 43 is connected by a wire 46h with the post 34aI anda pin 46 extends through an opening and is carried by the disc 47, the pins 46 and 46a. being adaptedto be'engaged by the contact segments 41 and 42, as clearly shown in Fig. 8, to effect 85 the reversal of the motor, thel wire 46c from the pin46 extending to the'motor eld coil and from it ,tothe ground.

The linger 38 has an extension A48 which termi- 90 gages a pin50 carried ,byan arm 51. The arm 51v is fixed on the shaft V'20 and is',`therefore, driven by the motor. v

A projection52 is'arranged on the disc 40 connected ,by springs 53 and v54 with the. ringer 38 andfextension Y48. The disc Ahas catch shoulders 55 and 56 lwhich vare adapted to engage pawls 57 and 58 pivotally mounted on a-screw 59. A spring 60 connects the pawls and yieldingly presses them toward the disc 40. Knock-out pins 61 and 62 extend from the pawls 57 and 58 and are in the path of the'nger 38 and extension 48. The operation of this reversing mechanism is as followsz-With the switch set to the wire 30 as shown the line is grounded through the plate 37a and iinger 38. The circuit through thewire 32, battery wire 34, line wire 46h to the pin 46a leads by way of the segment 42 to the pin 44 which is connected by the wire 45ato one of the brushes (not shown) of the motor. The opposing with the post 34a.

with the nger 37a and during this travel the spring 54 is tensioned drawing -onthe plate 40. The movement of the plate, however, is retarded, or resisted by the pawl 58. When the extension reaches the knock-out pin 62 it withdraws the pawl 58 releasing the plate 40 and the plate thensnaps, reversing the segments Al1 and 42. There is at this moment suiiicient over-run of the motor to complete the movement ofthe part 38 so as to break its contact from the platev 37a.A This movement closes the cover andy cutsout thedisplay of the signal as hereinafter described.

To open the cover the switch 31 is rocked closing the switch with the line 30a and opening the switch with the line30. At this point-the nger 38 is under the post 37 and exactly the ysame cycle takes place in reverse direction as above described nallyleaving the parts in the position shown in the drawings. It will be understood that the switch 3l is such that when depressed it closes the circuitf with the wires 30 and 31.

An electric light 63 is connected by a wire 64 The opposite side ofthe light is connected by a contactiinger 66 with a post 67. This post 67 .is secured Vin an insulating block 68 carried by the hinge pinv 4 of the cover. As the cover closes the contact 'plate'66'moves .oi` the post 67 on to the insulated block and thus vcuts out the light and as the cover is opened the plate reaching `the post automatically turns on the'light'. The 'rear end of the cover has a curved portion which is designed to contact withV the screw 67 if desired. The bolt 4 on which the cover is mounted vcarries the block 68, the block 68 being xedon the bolt by the contact screw 67. The bolt has a frictional "fit with the sides of the cover which permits it to be. turned to change the position of the contact screw 67. If, therefore, it is turned counter-clockwise, asobserved in Fig. 12 one-eighth of a revolution it will be in Contact Awith the plate 66 with the cover closeo'lV and will contact the rear end of the cover with the cover open so that so long ascurrent is in the circuit the light will continue. The cover is provided with glass covered openings 65 which are properly colored for parking lights. If, therefore, it is desired to use this light as a parking light vthe screw '67 is turned one-eighthy revolutionfrom what is' shown and under these conditions the light continues at all times serving as a parking light or in running conditions signal light.

A display deviceis formed of VLl-shaped seg-e ments 69 of transparent, preferably colored, ma' V terial. `These segments are pivotedtogetherv at.

as a' 70 and open and close by a fanwise movement. The lower segment is secured by a screw 71 to the rear face of the case and the outer segment by a pin 72 extending through a perforation 73 in the upper U section of the display device. The pin 72 is secured in the cover. It will be noted that the lever and link system heretofore described which communicates the motion of the motor tothe cover in opening and closing the same is arranged. within the U-shapedsecticns of the display device and thus concealed. It will also be observed that the light 63 is arranged tofradiate light to the inner surfaces of the walls of the U-section, the U-sections forming a space open'fto the light. In order to strengthen the U-sectionsistruts 74 extend from the links 5 and 8 and brace the sections near their periphery. What I claim as new isz- In a signaling device, an elongated casing having an open side, a cover for said open side pivoted at one endto said casing, a signaling element including a plurality of nesting U-shapedr transparent members pivoted at their similar legportions in the casing adjacent tothe cover pivot,
